Sexual selection can act in concert with natural selection on some of these same traits (as well as others), with complex results (e.g., ref. 11).
Exercise in Natural Selection
WebNatural selection and some of the other evolutionary forces can only act on heritable traits, namely an organism’s genetic code. Because alleles are passed from parent to offspring, those that confer beneficial traits or behaviors may be selected, while deleterious alleles may not. Acquired traits, for the most part, are not heritable. WebKey points. Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. frequency, … the history of kintsugi
